AUSTIN — A week after Longhorns used sex toys to protest Texas' new campus carry law, a Frisco-based gun-rights activist has released a video that depicts the fictional shooting death of a young University of Texas student.

Brett Sanders, who is perhaps best known for having paid a $220 traffic ticket with pennies, produced the video. He said he wanted to show the folly of the sex toy protest and the need for guns to be available for personal protection.

But a protest organizer said she felt threatened by it, in part because it uses the real names of some involved with the event. And a prominent gun rights group, Students for Concealed Carry, denounced the video as "reprehensible."

The video features a young actress playing a UT student returning home from the sex toy protest who is killed by a masked robber. After the robber breaks down her apartment door, the student points a large sex toy at the robber. He laughs and shoots her in the head before yelling expletives at her and calling her a "liberal."

"The entire point of my video was to drive home the fact that the anti-gun protesters are actually a threat to their own lives," he said. "Violent criminals do roam the streets and will always seek the path of least resistance. So, if you are threatening to disarm me or others, then you are actually threatening all of our lives."

Ana Lopez, a UT sophomore who helped organize the protest, said the student murdered in the video is meant to depict her. In the video, the student calls Rosie Zander, a friend of Lopez's at UT who was also a prominent organizer of the protest.

A video of Zander at the protest posted by The Dallas Morning News was viewed nearly 10 million times.

Lopez said that a gun-rights activist who goes by the name Murdoch Pizgatti "choreographed" the video, posted the video and the following message on Facebook: "A prominent member of Cocks not Glocks was murdered by senseless gun violence. My condolences to Rosie Zander for losing her best friend."

"I felt frantic and targeted. I knew that this was much more than a little 'gun nut' joke," she said. "This was sinister, threatening and dangerous."

Lopez has contacted the UT Police Department and student affairs about the video. University spokesman J.B. Bird said school leaders had just became aware of the video, which was posted on YouTube late Wednesday.

"When rabid gun fanatics can't win an argument, they resort to threats and publicly daydreaming and laughing about the rape and murder of their detractors," Jessica Jin, a UT alumna who thought up the sex toys protest, posted on Facebook. "They apparently can't wait for it to happen, because today they used the likeness of our activists to play out these murder fantasies in a violent video, to try to scare us into silence."

Students for Concealed Carry, a noted proponent of the law, likewise criticized the video as offensive. The group distanced themselves from Pitzgatti, saying that "to say that he is on the fringe of the gun rights movement would be to give him too much credit."

"All parties to the campus carry debate, regardless of position or affiliation, have a duty to stand up to such reprehensible behavior," said Brian Bensimon, the group's Texas state director.

Sanders said the only students who should feel threatened are those "stripped of their right to use a tool to defend their lives. If anyone is threatened by the content of a YouTube video in and of itself, I would say they are completely detached from reality."

He denied the actress in the video is meant to depict Lopez, saying he'd never heard of her.

On his website, Sanders describes himself as a "notable first and second amendment activist, Bitcoin advocate and investigative journalist based in the Dallas-Fort Worth area." Earlier this year, he made national news headlines for protesting a costly speeding ticket by paying for the fine with buckets and buckets of pennies.

"When my fine came due, I just decided I may as well pay with pennies and we'll make a big spectacle of it," Sanders told KXAS-TV (NBC5).

Campus carry took effect in time for this school year. The law, which took more than a year to implement, allows those with a specific gun license to carry concealed handguns into most campus buildings at Texas' public colleges and universities.

Some areas have been deemed off-limits by campus leaders at different universities. Responding to overwhelming opposition to the new law among professors, UT President Greg Fenves said faculty can ban concealed weapons in their offices. The decision has come under fire from gun advocates and statewide leaders, who say it violates the spirit and intent of the law.

A federal judge ruled that they were unlikely to win the suit. The professors continue to fight in court to overturn the law, saying it violates their constitutional rights to free expression and equal protection under the law.
